Three-piece construction with flat-locked seams provide a smooth, seamless feel that hugs the contours of your foot. 2 mm neoprene with titanium adhesive holds your body heat and keeps feet warmer without adding unnecessary bulk. Anatomically shaped left and right feet offer superior fit and unmatched comfort while eliminating the guessing game. Pairing snaps help prevent you from hitting the river with only one sock. For those shoulder-season days when it's too warm for dry socks but wading into the water chills your toes, the 2 mm neoprene NRS Wetsocks offer added cushioning and the right amount of warmth. Perfect for wearing with sandals or wetshoes.
